WINDOW-FRAME A-ND WINDOW-SASH.

SPECIFICATIQN forming part of Letters Patent N o. 683,077, datedSeptember 24, 1901.

Application filed August 24, 1899. Serial No. 728.326. (No model.)

To all whom it may concern; A

Be it known that I, HENRY C. SMITH, a citizen of the'United States, anda resident of Somerville, in the county of Middlesex' and State ofMassachusetts, have invented a new and useful Improvement inWindow-Frames' and Wiudow-Sashes, of which the following is a full,clear, and exact description, reference being had to the accompanyingdraw- Io ings, forming apart of this specification, in

explaining its nature.

The invention is an improvement upon that described in my applicationfor Letters Patent of the United States (Case A) ezgeclxted of even dateherewith; and it consists in a modification of the window-sashes in thatone or both of the side rails of the sash is or are made in twolongitudinal sections, the inner of which is united to the top andbottom rails 2o of the sash and the' outer of which is de- 3o site widthto fill the spaces between the stop- 4o sections of the frame.

beads by means of separate pieces, which are then united or joined tothe remainderof the sash by being slid vertically upon the incompleteedges thereof. These two sections of the side rails are so formed as tointerlock, and this construction of the window-sash permits the sidesections of the window-frame to be constructed with permanentstop-beads, which are integral with the rest of the side The sidesections of the frame in all other respects are like those described inmy said pending application.

In the drawings, Figure 1 is a vertical section of my improved windowframe and sash. Fig. 2 is a vertical section on the line 2 2 of Fig. 3.Fig. 3 is a horizontal section on the line 3 3 of Fig. 2. Fig. 4 isavertical section of the weight-adjusting device. Fig. 5 is a detailperspective view of the frame. Fig. 6

5o is a detail perspective of a portion of the rail. Fig. 7 is amodification to which reference will hereinafter be made.

dow-frame, B the upper window-sash, and C the lower window-sash. Thevframe is made 'of sheet metal and comprises the side sections d a', thesill-section 0,2, and head-section da. The sill and head sections areeach made ot' one piece ot' sheet metal, substantially as describedV inmy said application, and they are joined at each end with the lower andupper ends of the side sections. Each side section is also preferablymade of one piece of sheet metal and varies from the side section ofsaid application in thatit is provided with two additional integral stopbeads-namely, the outer stop-bead a4 and the inner stop-bead a5. 'lheseare formed integral with the plate from which the section is made bybending. As these beads are made before the frame is set and are notremovable, I have constructed the side rail of each window-sash in twoparts, the inner of which parts is attached to the top and bottom railsof the sash and the outer of which parts is detachable and attachable.This provides a sash which can be narrowed for insertion into the frameand can then be widened by the addition of the detachable sidesash-sections.

In the drawings,B represents one of the side rails of the sash, and b isthe section of said side rail which is rigidly secured to the upper andlower rails of the sash.

b2 is the independent attachable section of the side rail. Y

The section l) preferably is made of two pieces of sheet metal-namely, apiece which is shaped to form the part b3 and thev piece which is shapedto form the glass-retainer b4. The piece b3 forms the sides b5 bs, theinner edge 57, and the outer edge bs. The inner edge has the shoulderb9, against which the glass is set, and a section blo of a lock for theretainer b4. The outer edge bs of the section is formed of the two endsof the piece, which preferably are bent inward to form the beveledsection b, then outward parallel with each other, and then returned uponthemselves to form part-s Z112 of a joint by which the detachablesection b2 of the sash-rail is secured to it.

The detachable section b2 of the side rail A is made of one piece ofsheet metal shaped to provide the continuous edge face 513, the innorand outer side sections b1* Z915, and the inner sections bw. Thesesections are shaped to abut against the parts bil--that is, they areformed outward at an obtuse angle to the sides and are substantiallyparallel with the diagonal faces of the section b. They are also formedto interlock with the locking parts of the section b by having theirends b turned inward parallel with each other. (See Fig. 6.) The partsof the locking-joints are thus so formed that the detachablesection b2may be united to the section b by being-moved vertically from above orbelow in relation to it, the locking ends L17 of the detachable sectionbeing thus interlocked with the locking portions of the section b.

The glass-retainer b4 is made from asingle sheet of metal, hasthejoint-section D18, which interlocks with the joint b1 of the sectionb, the diagonal bracing edge b1, and hemmed outer edge Z920. It isbolted by the bolts b21 to the parts h. The mullion or center railD ofthe sash I prefer to make as represented in Fig. 3. l

E representsa sash-retaining spring united to the sash by fusible metalbearing against the casing and `designed to help balance a heavier innersash against a lighter outer ysash and also to release both sashes incase of heat from a fire sufficient to melt the attaching-solder. I donot, however, claim this spring and its use here, as I have describedandclaimed the same in the application above referred to.

l prefer that the sashes be hung as described in saidapplication-thatis, that the sashes be connected by a tape or wire cord F running fromthe top of one over a fixed pulleyfaud to the top of the other. Topermit both sashes to be closed, it is necessary that the connectingtape or cord should be of the proper length and have no slack or be tooshort, and as it would be difiicult tohang the sashes in a manner toprovide this proper length without some means for the `adjustment of thelength of the tape or cord I have provided one of the sashes with a cordor tape adjusting device consisting of alever G, to the outer end g ofwhich the cord is attached, and which lever is fulcrumed at g and isadjusted to raise or lower the said outer end g by an adjusting-screwg2, accessible from the top of the sash and screwing through a threadedhole in the end g3 of the lever. By turning this screw the end g of thelever is raised or lowered with respect to the top of the sash, and thesash tape or cord is lengthened or shortened thereby.

To hold the detachable section Z22 of the side rail of the sash inplace, I may use any locking device, and I have represented an anglo-iron I-I at the upper corners of the sash, which has a horizontalsection extending over both ends of the two sections of the side railonto the top rail, if desired, and a vertical section which extendsalong the outer or inner surface of the detachable section and which isunited to the side sections by rivets or bolts. In lieu of adjusting thej end or ends of the sash tape orA cord the pulley over which it runsmay be made vertically adjustable.

In practice, the detachable sectionsA of the sash being first set intothe proper pair of r grooves in the side frames-for example, the 75grooves a-the sash is then moved vertically so that the interlockingends b slide into their appropriate grooves. It will thus be seen thatthe window-frame itself does not have to be taken apart in order toreceive the window-sash, as is the case with the ordinary window frameand sash.

In Fig. 7 I have represented the windowsashes as counterbalanccd'byweights in the ordinary way, and when they are so 'hung I prefer toemploy a metal window-frame having weight-holding metal cavities and tomake engagement between the sashes and the weights in the cavities inthe usual way.

The window-frame when so constructed 9o `may be made substantially inaccordance with that described in my application for Letters Patent ofthe United States, filed May 31,1399, Serial No.7l8,794, and allowedAugust 7,1899.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United Statesl. A window-sash having a siderail made `in two longitudinal sections, one of each sections forming apermanent part of said sash, roo the other of which is detachablysecured as described, said sections having a bearing against each otheralong their entire length whereby one section of said sash is renderedincapable of any swinging movement relative to the other and bothsections are adapted to be moved together vertically in the windowaframe, as and for the purposes described.

2. A metallic window-sash having a side rail in two sections, one ofwhich forms a 11o permanent part of the window-sash :and is formed tointerlock with a portion of the other section of the rail, said othersection of the rail being detachable from the iirst-'named section andhaving interlocking sections to engage the interlocking parts of thepermanent section of the rail, the interlocking sections of the saidremovable section engaging the interlocking sections of the Iixedsection by a longitudinal sliding movement of one upon the other.

3. The combination of a metallic Window; frame having permanent frontand back stop beads and a permanent central stopbead, a metallicwindow-sash having a side rail in two parts or sections the outer ofwhich is removable from the inner to narrow the same and is attached tothe inner after the sash has been placed in position in the frame by avertical movement with respect thereto, whereby the sash is made to llbetween two of the beads.

4. The combination of awindow-frame hav-V ing permanent front and backstop-beads and 5. The combination in a metallic Windowsash of the siderail made in two sections or parts one of which is detachable by alongitudinal movement with respect to the other and attachable in thesame way thereto, and means for locking the two sections of the sashtogether when in engagement.
